Two quick suggestions, from the top of my head:
1) Make sure to check the output of the CULA routine - there's a chance that some of these cases are erroring and therefore exiting early.
2) Try reusing the same A matrix each time you repeat the same test size. Eigenvalue convergence is highly data dependent, so it's hard to make guesses when the data varies each call.
